Kevin can't even eat!

NOW that Britney Spears has called a halt to Kevin Federline's gravy train, the aspiring rapper is broke. Even before the split was announced, Spears told Fed-ex to fly himself to New York and get his own hotel room, an insider told Us Weekly, even though she was flying here on a private jet to record music. Spears then ordered his phone turned off and credit cards shut down. "Not even his mother could get ahold of him," a source told the magazine.

Federline is now scrimping where he can. He and his entourage of eight wannabe rappers showed up at downtown burlesque joint Corio for a comped dinner that would have cost him $1,200, a source tells us. An eyewitness at the next table reports, "He just kept ordering more and more food and then asked for it to be put in containers so he could take the food out to the clubs with him. Then he started putting napkins in the tops of the tequila and vodka bottles and stuck them under his coat trying to sneak the liquor out with him. It was really unbelievable to watch. The guy obviously has enough money to buy a bottle of liquor on his own without trying to sneak it under his coat." Well, maybe not anymore.
